Supercar fan James May says he wants the speed limit on most of Britain's roads reduced to 20 miles an hour.
The former Top Gear presenter - who was nicknamed 'Captain Slow' on Top Gear by co-stars Jeremy Clarkson and Richard Hammond on the show - says 30mph is just too dangerous.
Ministers who have already cut the limit says it helps reduce road collisions and traffic noise, and may even encourage people to walk and cycle more.
